Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 11, 2023The c.1870A>G (p.K624E) alteration is located in exon 17 (coding exon 16) of the CCDC178 gene. This alteration results from a A to G substitution at nucleotide position 1870, causing the lysine (K) at amino acid position 624 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
